Discovery of cell-permeable OGT inhibitors is significant to clarify the function and regulatory mechanism of O-GlcNAcylation. This will establish the foundation for the development of therapeutic drugs for relevant diseases. Here, we report two cell-permeable OGT inhibitors (APNT and APBT), developed from low-activity precursors (IC50 > 1 mM) via “tethering in situclickchemistry (TISCC)”. Both of them were

alkyl optionally substituted by OH or halogen. This is prepared by the steps of:
(a) enantioselective (R)-esterification of the racemic alcohol using any acyl donor and a first enzyme;
(b) removal of the untreated (S)-alcohol; and
(c) enantioselective hydrolysis of the (R)-ester, using a second enzyme.

A propargylic alcohol, enriched in the (R)-enantiomer, has formula (I) wherein R is C1-4 alkoxy, halogen, or C1-4 alkyl optionally substituted by OH or halogen. This may be prepared by the steps of: (a) enantioselective (R)-esterification of the racemic alcohol using an acyl donor and a first enzyme; (b) removal of the unreacted (S)-alcohol; and (c) enantioselective hydrolysis of the (R)-ester, using a second enzyme. The alcohol can be converted to a prostaglandin by known means.
aging, sagging, and wrinkling, as well as inflammation and bacterial infections. In this study, to identify novel hyaluronidase inhibitors, we applied click chemistry for the modular synthesis of 370 triazoles in 96-well plates, starting with biphenyl azide. Utilizing an optimized turbidimetric screening assay in microplates, we identified Fmoc-containing triazoles and , as well as quinoline-containing
